Hi Team,

As we re using the LM1815 in our design.

As per the datasheet Vout(High) is Minimum is 7.5 Typical is 8.6.

We are supplying the Vcc pin with the 3.3V.

Operating in the MODE 2.

If we supply Vcc pin with the 3.3V, then what will be the output range at the pin No. 10?

Hello,

If the VCC supplied is 3.3V, then the max output on pin 10 will be 3.3V.

Regards

Hi Team,

In continuation with the above query,

What is the Max input voltage at the Vin pin for the supply voltage of the 3.3V at the VCC pin?

Hi Rajeshkumar,

Reading through page 8 on the datasheet, there is a section called Input Voltage Clamp. Per my understanding, you should not send a signal to the Vin pin that is greater in amplitude to VCC, since Vin will be clamped to VCC internally.

Thanks
